DN25 1 diax200mm long Double sphere rubber expention joint
Key Specifications

• Nominal Diameter (DN): DN25 (1″ thread size / 1-inch) 
• Length: 200 mm 
• Axial Movement: ±22 mm 
• Lateral Movement: ±22 mm 
• Deflection Angle: 40° 
• Common Materials: EPDM, NBR (Oil-resistant), CR, or FPM elastomer bodies combined with nylon cord reinforcement and steel flanges or threaded unions. 
• Working Temperature / Pressure: Typically rated up to 150°C (depending on the rubber compound) and standard PN10/PN16 or 150 lb class pressures. 

Main Functions

• Vibration & Noise Dampening: Isolates equipment like pumps and compressors from the rest of the piping network.
• Movement Compensation: Absorbs small axial compression/elongation and lateral offsets. 
• Water Hammer Reduction: Softens hydraulic shocks and surges to protect pipeline integrity. 

If you'd like, let me know:

• What fluid or medium (water, oil, gas, chemicals) will flow through it?
• What end connection you need (threaded union or flanged)?
• The operating temperature and pressure of your system?

I can help you pick the right rubber compound and standard for your setup.
